Abstract

Background:  Titanium remains the gold standard for the fabrication of oral implants, even though sensitivity does occur, though its clinical relevance is not yet clear. Placing permanent metal dental implants in allergic patients can provoke type IV or I reactions. Several symptoms have been described, from skin rashes and implant failure, to non-specific immune suppression. Material and methods: The present observational study was conducted among 300 volunteers of 25-60 years. Test allergen composed of titanium dioxide 0.5% in petroleum base was used to assess the allergic reaction. Results were compared by z-test. Results: Seven out of the 80 patients with history of allergy shows positive results. One out of 120 without history of allergy shows positive results. p-value is found to be significant (˂0.01) Conclusion: Ti allergy can be detected in dental implant patients, even though its estimated prevalence is low. We suggest an examination of pre-implant patients who have a history of hypersensitivity reactions to metals.
